To all whom it may concern."

.Be it known that I, FRANKLIN New York, have invented a new and-lmproved Side-Dumping Boat, or which the following is a tull, clear, andexact descrip? sides will swing outwardly and downwardly.

during the dumping operation sov that there i will be a quick release of the load on both sides in order that the equilibrium or the boat maybe maintained.v l.

A still further 'obiect oi' the invention is toY provide a side dumpingfboat iny "\vbi cb means are provided whichwill permit the doors or side members to be quickly swung back to their former operative'position.

fin the accompanying drawingsy Figure l is a top plan view .of a boat disclosing an embodiment yoit the invention7 certain sections of the boat being shown in a dumped position.

Referring to the accompanying draw ings by numeral, '11. 'indicatesv the boat or ,55 scow which is provided'with. a bottoni l2 et any usual .0.1" preferred constriictlsin` and,

ThebottomllQ is connected-with the side walls lefand l5 of 'suitable construct-ion, said side walls extending a short distance above' the bottom where they mergeinto the inclined bottoms'l and 17,v said bottoms having'the appearange ot' an A in `cross section. as illustrated in FiguresB, 6 and 7. At each end of the bottoms v16 and 17,y there is a bulkhead and these` bulkheads vare designated by therel-er'ence characters 18 and 18. Along the topfedges and l5 are hingedI a plurality of doors 23 and 24, there being in the present instance four doorson each side of the boat;

As indicated in Figures@ and these doors Aare closed or in avertical` position, the sides oit theiboat arey closed and' ready to receive a load. When it is desired to discharge this load. these doorsv are re-y leased and allowed'to move down under the .ictioiiQot gravity and the pressure or the load until they assume substantially the ypo. sition shown in Figure 3. This will' allow` of the sidewalls 14 7, .when

the load to slide ofi into the water *automatacally. rlhis construction and arrangement of side-dumpingboat maybe used for various purposes but it is particularly'adapted 'for ti`"a.nspoi.tiiig` mattery tothe rocean and dumpingthe same thereint-o'.

After the load hasy been .dumpedsthe chains 25,;.26 and 27 are wound on theirl respective drums 28,y 29 and 80. These drums `rnay be of any suitable kind and` .mounted upon a shaft 3l supported by suit-` able standards 'and operated by a ratchet wheel 32rigidly securedto shattl. The

ratchet v wheel 32 lis. engaged by a 'suitable p'awl 83 for normally preventing a reverse movement and engaged by a ypawl 3e voperated by a lever 85tor rotating ina directioii`- tor raising the doors 23` and-y 24; lt will be note-d- Yfrom Figure 3 that suitable guide rollers 36 'and4 37 fare provi'ded`to-guide the chains on the opposite their respective drums.

lhis' upwardmovement is continued under I the pull oi .the chain 26 until the parts assume substantially the position shown in dotted lines in igure '7'. When the parts are in this position, the strain is transferred te the rGSPeCtive chains Q5 and 27 ivhi'ch iinish the closing movement of the doors. it, vill he noted that these chains are connected to the respective-bracinbars 4e. said brat ing' hars beingpivota'lly mounted at their outer ends to the upper edge of the doors and at their `inner endsprovided With endoors and 'again restore them.

lily this construction 'and arrangement the bracing bars 44 act as elevating means 'for ashoit distance and then act to holdA the door against either inward or outward swinging movement. The` chains Qand 43 are so proportioned as to be automatically aken up as the respective chains 25 and 2T close the door. Usually the iiilcrnm lever 38 assumes" the position shown in Figure 6 when the gate has been Completely closed, As indicated in Figure 3. the respective chains 25 and 27 are proportioned to be very slack -when the lrates are completely open in order that the drums may properly Wind up these chains` andechain 26 simultaneoiisly.

As indicated inr Figures 3, G and?, a` plat- `Form 47 is provided beneath the inclined floors 1G and 1T, saidplat'iiorin providing designed to abut against the ample kspace tor a Workman when actuatingor releasing' the doors.

Also, this arrangement of releasing and closing;` otthe doors may be readily performed in' almost anyv kindofa sea, that is', Whether the'vvaves are rhigh orloW; I It will benot'ed that the By 'quickly etheboat body at the bottom ol said inclined Hoor members, said doors when in a 'vertical' position lacting` as side Walls, a phirality ot chains connected with said doors, drums for actuating said chains for causing the chains to close thedoors, and a pulling and bracing har normally7 extending' 'betn'een the reeend ot the door and the upper end oi the inclined members iter each door ttor limiting the closing action.
